====================
Intel Wired LAN Driver Updates 2015-08-05

This series contains updates to i40e, i40evf and e1000e.

Anjali adds support for x772 devices to i40e and i40evf.  With the added
support, x772 supports offloading of the outer UDP transmit and receive
checksum for tunneled packets.  Also supports evicting ATR filters in the
hardware, so update the driver with this new feature set.

Raanan provides several fixes for e1000e, first rectifies the Energy
Efficient Ethernet in Sx code so that it only applies to parts that
actually support EEE in Sx.  Fix whitespace and moved ICH8 related define
to the proper context.  Fixed the ASPM locking which was reported by
Bjorn Helgaas.  Fix a workaround implementation for systime which could
experience a large non-linear increment of the systime value when
checking for overflow.
